Common, you have a R3 and want to spend only 150 bugs on a remote control ???
Pay 1.000 and buy the one from PHILIPS or MARANTZ, color touch panel and easy to program. I don´t know the exact model in the US, but should be very easy to find in a good A/V dealer.
You always can spend 10 times more for an AMX or CRESTRON unit, but I should better buy another bike !
